Benefits of technology
The system ensures uninterrupted voice and data traffic by providing a reliable and efficient power supply, reducing environmental impact and maintenance needs while optimizing space usage.
Problems solved by technology
For instance, at a remotely located telecommunications facility, such as a wireless communication site (a “cell site”) utilizing a base transceiver system (station), the loss of power from a commercial electric utility typically results in a “dead area” where no wireless communications are supported by the particular cell site.
Even more critical is the maintenance of reliable and adequate power at a telecommunications exchange (switching office or subsystem) or a point of presence server, since power loss would result in the disabling of one or more telephone switches or critical gateways to the Internet, thereby affecting large volumes of voice and / or data traffic.
There are many disadvantages, however, to each solution.
Among other things, diesel generators often emit large amounts of pollution during operation, and are also prone to mechanical breakdown.
Furthermore, such generators and the accompanying fuel storage device for supplying fuel take up significant amount of space per unit of power produced, making such devices unsuitable for use at telecommunications sites where space is critical.
Lead-acid batteries also require significant maintenance over time, and may post a health and environmental hazard due to the corrosive gases produced by the batteries.
Another drawback of lead-acid batteries is that such batteries suffer from a declining ability over time to hold a maximum amount of energy, which results in the useful lifespan of such batteries oftentimes being shorter than a rated lifespan for the batteries.

Embodiment Construction
[0017]Embodiments of the present invention relate to power system for a telecommunications network. One exemplary diagram of a simplified set of sites or facilities that handle voice and / or data traffic along a telecommunications network is provided in FIG. 1. A plurality of cell site facilities 1000, or wireless communication facilities that each have a base transceiver system, or BTS, (also referred to herein as a base station transceiver subsystem), are linked to a central facility 2000 serving as a telecommunications exchange (also referred to herein as a switching office or a network switching subsystem) or a point of presence (POP) server. The cell site facilities 1000 combine to provide wireless communication coverage areas for mobile device users engaging in voice or data communications. The central facility 2000, as one example, carries out switching functions and manages communications activity between the mobile device users serviced by the cell sites 1000 and the public ...

Abstract
A reliable, end-to-end power supply solution for components of a telecommunications network provides either a primary source or a backup source of electrical power at various telecommunications sites for reliable operation of telecommunications equipment. One subsystem of the power supply solution includes one or more proton exchange membrane type fuel cells and an energy storage device for storing DC electrical power produced by the fuel cells. Another subsystem includes one or more microturbine generators, one or more rectifiers for converting AC electrical power produced by the microturbine generators to DC electrical power, and one or more proton exchange membrane type fuel cells for producing DC electrical power. The power supply solution ensures that voice and data traffic is reliably handled by a telecommunications network in situations where commercial electric utilities fail to supply power at certain points along the network.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of and claims priority to U.S. application Ser. No. 11 / 132,013, filed May 18, 2005, and entitled “POWER SYSTEM WITH REFORMER”, the teachings of which are incorporated herein by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.BACKGROUND[0003]Telecommunications service providers are increasingly concerned about maintaining reliable network connections for both voice and data transmissions. One particular area of concern is the maintenance of an adequate power supply at various sites along a telecommunications network in order to ensure telecommunication equipment and facilities housing such equipment are functioning properly. For instance, at a remotely located telecommunications facility, such as a wireless communication site (a “cell site”) utilizing a base transceiver system (station), the loss of power from a commercial electric utility typically re...
